Unless you are very wealthy or extremely good at winning lotteries, you can expect to be working for 40 years of your life or more. And while not everyone has what it takes to become a top executive, you do have complete control over how far you go and how much you earn in your career.

You can crack the corporate success code! But only if you stop making career-killing mistakes...

Here are the Top 5 Career-Killing Mistakes People Still Make & Then Wonder Why They're Not Advancing Their Careers:

Career Killing-Mistake #1: Not knowing the real purpose of your resume.

Of all the things critical to landing a great job, having a great resume isn't on the list because that's not its real purpose! And you cannot create a killer resume if you don't know what that purpose actually is.

The purpose of your resume is not to get the job. It's to be selected for the short-list of people that the employer wants to interview. This decision is made in less than 10 seconds and NOT by the hiring manager. It's usually an administrative assistant who looks at the submissions and it takes him/her at least 3 seconds to look at your name! Not understanding this means most resumes are thrown in the trash immediately

Career-Killing Mistake #2: Not getting the answer to the most important question of all before you start answering your interviewer's questions.

The hiring decision is made in the first four minutes of a job interview. Everything that happens after this only serves to reinforce your interviewer's decision. You HAVE to get the answer to this question before time is up: Are they looking to hire MORE people like those they already have on the team/in the department or are they looking for people who are DIFFERENT from those already on staff to inject new blood/fresh thinking into their organization? The answer to this question will determine how you respond to their questions. Otherwise, you'll just be wasting their time and yours.

Career-Killing Mistake #3: Believing the key to success is working hard and putting in long hours then making sure your boss knows about it.

Most people believe ensuring people know how hard you are working is the #1 key to getting ahead. No -- A thousand times no! This is actually one of the fastest ways to hold yourself back in your career! In fact only 3% of people working hard ever experience success. And this career-killing mistake is not good for your health either.

Career-Killing Mistake #4: Not doing the one thing that renders all on-the-job competition irrelevant.

The one thing is taking ACTION. Taking action requires no special tools or intelligence. And 98% of your co-workers will NOT be doing it.

In any organization there are always a bazillion things that need to be done. However, 10% of the employee population will make professional commitments to getting thing one with enthusiasm. And only 2% ever actually take action.

Management has to constantly CHASE and FOLLOW UP with the other 98% if they want to make sure things are getting done. So what this means is if you work in a department of 100 people, only 10 people will have high potential and only 2 people will be in direct competition for raises and promotions

So, if you're not taking action you are automatically keeping yourself from getting ahead and won't be taking home the paycheck you deserve.

Career-Killing Mistake #5: Not setting up an employment file at home and not checking what the employer has in your personnel file once a year.

No one will ever care more about your career than you do. Create your own employment file and keep it at home.

Also, once a year, make an appointment with Human Resources to review your personnel file. Mistakes happen. Only you can make sure all the good things that should be in your file are actually there. Opinions (strong ones) of your worth to the employer are formed on the basis of what is found in that file. Don't let the wrong ones be made about you.
